Texas Rep. Al Green was one of the thousands that gathered Thursday night at a rally in the hometown of Trayvon Martin protest the lack of action that had been taken on the investigation.

Green, a Democrat from Houston who attended grade school through college in Florida, said the incident has become a national issue.

“I’ve had many, many people stay this happens too often,” Green said. “This does not look right.”

Martin, a 17 year old, had been walking through a gated community in Sanford, Fla. last month. George Zimmerman, a self-appointed neighborhood watchman, shot and killed Martin because he said he felt threatened by him. Martin had been unarmed.

Although it has been nearly a month since Zimmerman shot Martin and has stated that he was the shooter, he has yet to be arrested or charged.

Thousands gathered for the rally, some wearing hoodies with the hood up and holding Skittles and iced tea – imitating what Martin had been wearing and carrying when he was shot. The event, organized by the Rev. Al Sharpton, was also attended by Martin’s parents and Dr. Martin Luther King III – the son of the famous civil rights activist.

“Something has gone wrong in our nation when vigilantes can go around under the pretense of protecting a neighborhood and just kill people,” King said in an interview with the Houston Chronicle. “Any member of congress ought to be concerned about this because it impacts all of our children.”

This is the second protest Green has attended in a week – last Friday he was arrested protesting outside the Embassy of Sudan, the same protest George Clooney was arrested at.

“I regret I don’t have enough time to take on all of the challenges,” Green said “People protesting has proven to be one of the best means by which we can have action taken.”

Green did not know of any other Texas Congress members who made the journey to Florida, but he has not been alone in supporting more action be taken on the Martin case. Houston Rep. Shelia Jackson Lee sent a letter to the Department of Justice asking them to conduct an investigation of the shooting, which the DOJ announced they would do on Tuesday.

“We need a through investigation so the public can know exactly what happened,” Green said.

There has been debate on whether the incident should be regarded as a racial issue – Martin was black, Zimmerman was half-white, half-Hispanic. But Green said for him, it was about the larger picture.

“Regardless of race, ethnicity, religion – it doesn’t matter,” Green said. “What matters is that the person has lost their life.”
